it all depends really, the gun doesn't make the user, I've seen all different guns in all different hands and sometime the shittiest shotty will work like a fireing squad in the hands of the right guy

you really get what you pay for more so when it comes to shotguns.

the two most used models are the TM M3 shorty and the Crosman s34p a M3 clone. both are spring powered and are ok, great for cqb and are spring powered easiet to get ahold of, no shell eject though.

gas powered shotguns are expensive, especially shell ejecting ones but their pure awesome. but you gotta go around and pick those expensive shells up after the game, you'll often loose one or two per game and that tolls up avantually

shotguns come in all different systems, single shot (one bb fired only) tri shot spread (3 bb's fired) gas powered non shell ejecting, gas powered shell ejecting, just spring (these ones usually hold more rounds than the gas powered)

the Maruzen CA870 shotguns are pretty beasty and can be changed around a thousand ways from full size/stock to a shorty defender to a masterkey. but the parts to do such are becoming few and far between.
you don't want any ACM shotguns their money pits and often break on the first run, always need fixing.

I just sourced a Spas 12 with folding stock it's on it's way to me I'll post what I think about it when I get it in the mail.
